SPRAYING-NOZZLE.

Specification of Letters Patent.

Patented Nov. 27, 1906.

To all whom it may concern:

v Be it known that I, CHARLES A. KoEPNIox, a citizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Spraying-Nozzles; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

This invention relates to new and useful improvements in spraying-nozzles, and possesses the novel characteristics and the advanta es hereinafter described and claimed.

In t e drawings'annexed hereto, Figure 1 is a side elevation of the improved nozzle detached. Fig. 2 is a sectional view of the same with parts broken away. Fig. 3 is a detached lan view and side elevation of the inner diap agm.

In a detail description of the invention similar reference characters indicate corresponding parts.

The nozzle-casing 1 has a branch 2, by which it is united to a hose or other medium of inlet for-the liquid to be introduced to said nozzle. Passing upwardly through an end of said. casing and a suitablestufiing-box located therein is a stem 4, the end of which has a flange 17, between which-and the end of the nozzle a spiral spring 8 is placed around the ex o'sed end of the stem to normal] hold sai stem in the position shown in the rawings. The stem has upon its inner end a needle 16, to be again referred to. The end of the nozzle is closed b a screw-threaded lug 3, through which t e stern passes.

t the dischar e end of the nozzle there is a thin metallic disk or diaphragm 5', which has a central orifice 10 and a series of radial orifices 9, which are formed by providing a series of tapered tongues 10, which are stamped from the diaphragm and which provide a series of deflecting-surfaces to cause the li uid entering the orifices to be thrown latera y against an outer diaphragm 11. These two diaphragms 5 and 11 provide a vortex-chamber 7, into which the liquid is thus discharged to impact with the diaphragm 11. These two diaphragms are maintained in position in the mouth of the nozzle by means of a cap 13, which screws onto the exterior of the nozzle and is open to expose the diaphragm 11. The said diaphragm has a central orifice 12, which is in alinement with the orifice 10 of the inner diaphragm 5. The needle 16 is movable through the orifice 10 and the orifice 12, the latter orifice being the sprayingoutlet through-the diaphragm 11. The orifices are thus ke t open and free from an accumulations w ich may tend to close t e sprayingorifice 12.

I claim In a s ra 'n -'nozzle, a casin a s ra disk or giag hr m having a c ntra oriii d and located in t e discharge end of the nozzle, a disk or dia hragm located adjacent to said spraying-dis and providing a vortex chamber between the two disks or dia-
